ok dx to zc swap ive had it for almost a month and the ecu is giving me code 4 (crank posotion sensor) and im not shure how to fix this i think it is whats causing my car to max out at about 3200 RPM it bogs when i try to go above this on all gears any one else had this problem please help

 

u either have a bad dizzy or u wired the MPFI (distribuitor part wrong)

do a search on DPFI to MPFI
and double check that u got all the distribuitor cables u got them to the right spot

 

if i have learned anything in the past couple of weeks its that when honda gives you a code 99.9% of the time it will protain to the part that the code is being given off for. some people might tell you to replace this and replace that. I would use the helms manual to go threw step by step and troubleshoot that problem. it probably involves checking restistances/voltages with a multimeter. here is the link to the online helms manual. good luck

thnks guys if there are any more opinions feel free to put in your two cents thanks again every one

 

I had my car throw a code 4 once. Replaced the dist. and that fixed it. Unless you got the crank angle sensor wired backwards check that out.

 

Have you had this problem ever since the swap, or just recently? If you hooked everything up right and ran the correct wires to the crank position sensor (on the end of the exhaust cam, on a ZC its not in the distributor) I'd say go back and check your wiring (dpfi-mpfi) if that checks out ok, and if you have buddies with older integras or ZCs try to borrow one of their sensors (or hit the junk yard)

 

Make sure your timing belt timing is correct.

 

it's usually one of three things:
#1 you wired it backwards
#2 The sensor is bad
#3 Bad dizzy
that's about it

 

I suggest check with the helms manual and do every step as they tell you.. it usually fixes all my problems... if you dont have the manual, i know that there is one posted online.. but i dont know the url... ask around..
